' Renewed May 12, 1931 12 Claims. (Cl. 16-163) The present invention relates to hinges and more particularly to hinges especially adapted for use on the hoods of automotive vehicles.

. Among the objects of the invention is a hinge structure that shall be capable of sealing the hood againstthe entry of dirt and moisture.

Another object is a hinge that is easy and economical to construct and assemble, and efiicient in operation.

Other objects will readily occur to those skilled in the art upon reference to the following description and accompanyingdrawing, in which Figure 1 is a perspective view. of a hinge embodying the present invention, and showing one 1 end thereof.

Figure 2 is a sectional view of another form'of the hinge. I

Figure 3 is an enlarged sectional view showing theideal form of the beads. In the drawing the hinge structure is showing of a form suitable for application to an automobile hood, that is, the protective covering usually placed over the motor. As is well known, such cover is usually hinged along its central longitudinal line and in such fashion as to permit the opening of either side in case it becomes necessary to do so.

In both figures oi thepresent drawing, the hood proper is shown as formed of two sheet metal leaves 10, each provided with a depending flange 11 by means of which it may be secured to the hinge structure, as by means of the rivets 12.

The hinge structure is shown in botlr es as consisting of three parts, a body portion that I 95 remains substantially stationary when the device a is in use, and two angularly movable portions that r are adapted to be secured to the hood proper as mentioned above.

In Figure 1 the body portion is shown as consisting or a strip of sheet metal bent longitudinalLv to form an arched central rib or head and having its edges curved under to form one portion of a hinge such as is shown in prior application Serial No. 171,474, flled February 28, 1927, or in 1 Letters Patent, No. 1,666,211, issued April 17, 1928, both in the name of the present inventor.

' In this figure, the body portion is indicated at 15 merging into the curved bead 17 which is Iormedinto substantially a semi-cylindrical part 18, with the edge portion 19 turned up approximately vertical. The extreme edge portion 20'is provided with a further curved portion having a radius much shorter than that of the part 18.

56 The hinge portions on both sides or body 15 are similar in form except that they are reversely curved and formed.

The other hinge part consists of a strip of metal a in section substantially like an inverted L, the vertical stem 25 being the portion to which the hood member 10 is secured. The horizontal portion 26 of the strip has its edge formed into a downwardly extending bead 2'7 semi-circular in section on a radius of such length that it fits snugly within the semicircular portion '18 of the bead 17, while its extreme edge portion 28 is bent up close to the'vertical but at a slightly greater angle thereto than is the portion 19 of the outer bead. 7

Further, this edge 28 is of such length that the curved portion 20 of the outer bead overlies or extends beyond as shown clearly in the drawing. This slight difierence in the angularity of the edge portions 28 and 19 causes the former to press against the latter and obviate any relative movement of the two parts.

In the operation of the hinge, the member 15 remains stationary and the inner curved edge 2'7, which acts as the pintle portion rotates within the part 17.

In the open position of the hood the hinge part carried by the hood members 10 engages the radially extending portions. 19 of the other hingepart to limit the pivotal movement of the hinge parts in this direction.

In the form of hinge shown in Figure 2 the parts corresponding to those shown in Figure 1 are the hood members proper indicated at 10, the short strips to be riveted thereto are shown at 35 while the central member is indicated at 36. 90 In this form of hinge the central member 36 will be bent transversely to form the arched central portion and will have its edges curved in substantially the same, sort of curve as at 18 in Figure 1, these curved portions'being indicated at 37.

The curves, however, will be upward instead of downward as in the case of Figure 1. Also in this form the members 35 will be bent or curved inwardly as shown at 38 to give the same form to the hinge parts as has been described in connec- 100 tion with Figure 1.

In the opefition of the hinge of Figure 2, the two curved edges will occupy the exactly reverse positions in opened and shut positions, to the corresponding positions of ,the parts of Figure 1. 105 That is, in Figure 1 when the hood is down, the

hinge parts are turned into each other as far as possible while in Figure 2 they are turned out of each other.

In either case the hinge isclosedtiroughoutits n length to the passage therethrough of water or dirt and thus effectively protects the parts within the hood.

While it is preferred to form the lJ-shaped strips separate from the hood leaves proper, this is solely for convenience in manufacturing as the inner beads obviously may be formed integrally with the hoodmembers if found desirable. Figure 3 shows an ideal section, though this will of course be varied somewhat in the production of the hinge in quantity due to difliculties in handling thin metal, This figure shows clearly .that all of the curves are concentric with the com mon axis lying in the central plane of the strip A and-at such a distance from its inner edge that the distance tothe edgecorners equals the thick- .ness ot the metal. This latter distance is also the inside radius of the curve B. The radius of the inner curve of the part C equals the radius of curve B plus .the thickness of the metal. The

a radius of the inner curve of part D equals the radius of part C plus the thickness of the metal. Such proportioning of the parts provides for maintaining the curved surfaces. in contact dur; ing the hinging movement, so as to cause smooth operation and exert suflicient friction or pressure between the parts to prevent rattling even when they are most nearly disengaged.
